This is a quick and simple pun on the expression gentlemen prefer blondes, nothing more. It's one you can look at, grin, and move on without giving it further thought. It certainly doesn't merit any more attention than that.
In the years since I drew this, I've come to realize just how racially biased the expression gentlemen prefer blondes is. Having blonde hair is certainly a quality that is limited to the caucasion population, but whites hardly have a corner on the "gentleman" market! So under that light, one could say that my revised version is far more culturally sensitive than the original! Alas, that fact still doesn't make it any funnier, which is the real purpose for having a cartoon. Oh well, move along... I've already spent more effort on this cartoon than it's worth.
